Introduction/motivation Expert systems in student advising Advising process, advising system Designing the system with Exsys CORVID conclusion

The NEED for an automated system

Lot of transfer students Student’s availability is limited Many new faculty members Online education

Constraints of Selecting classes

Course prerequisites Actual class openings Degree check requirements Student’s availability

Online advising systems Implementation techniques

Client-side scripting: javascript Server-side scripting: active server pages

Web-based interactive student advisement(Tang,Fluker&Zeng,1999)

Applet: Java Michigan Technology univ.(Morrison,2003), Duisburgh Univ. (Wer

Expert systems shells Exsys Corvid (Awad, 2002)Complex expert systems techniques to deliver highly effective e

xpert knowledgeGiving students advice online through expert systems

Advising Process

Degree check requirements Student special interests

Structured degree programs Less rigid programs

Taking the course which is the prerequisite for largest number of other courses guarantees the shortest study time

Advising System

Names of departments involved in selected courses within sectionsHas to satisfy the number of units required for sections and categoriesHas to satisfy constraints related to the number of departments involvedStudent’s interests, student’s availability

Goal: automate the student advising process in General Studies Program

Designing the System with Exsys CORVID

Conversation in decision-making process within webpage

Inference engine: analyze and combine individual rules to solve larger problems, to determine what possible answers

Exsys CORVID

Example rule:Which of the following social science

courses have you completed so far?

Then:

[SS] is giving the value [SS]+3

And [FLAG6] is given the value 1

Eg.POL_100&GEO_100

Student’s availability?

Interests?

conclusion

Has been tested for 1 semester, 18 qualifiers, 64 choices(courses), 16 numeric variables, 243 rules

Possibilities: play it real!
